Application md December 1o, ieee. seria; No. 679,566.

To all whom t may concern:

Be it known that we, GEORGE S. LEINER and CHARLES A. BERNsTnIN, citizensof the United States, and residents of New Rochelle, county ofWestchester, and State of New York, and of the city, .l county, and

State of New York, respectively, have invented a certain new and usefulImprovement in Brushes, of which the following is a specification.

The object of this invention isto provid la brush used for cleaningpurposes, scrubbing, polishing surfaces, Washing of windows and thelike, which will be of strong 16 and sturdy construction, capable ofstanding considerable hard usa e, and. which will, by reason of itsconstruction be particularly adapted for the nature of the .work towhich it may be put. f ,d

With these objects and such other objects as may hereinafter appear, wehave devised the particular arrangement vof parts set forth below andpointedout in the claims appended hereto. V

Reference is to be had to the accompanying drawing, forming a partthereof in whioh- Figure 1 is a plan view of our improved brush, partsbeing broken away and in section, to disclose construction,

Flgure 2 is a sectional view on the line 2 2 of Figure 1, looking in thedirection `of the arrows.

Throughout the various views of the drawings, similar referencecharacters designate similar parts.

In the accompanying drawing, 1 indicates the wire core of the brush.This is preferably construcbed of a single section of twisted wires madein the form of a continuous loop. The bristles or other materialutilized 2 are secured to the wire core in a customary manner vbyholding the` same between the twists of the'wire strands which make upthe core 1.

At a substantially central point the'twisted wire core 1 is bent to forma. connecting bar 3 which has its end 4 permanently joined to the end`ofthe wire core as at 5 by welding or any other method. The weld ispreferably formed by interlacing or overlapping the two wires from bar 3and the two .wires from the other end of core 1, and then welding,whereby the ends are in eifect both spliced and welded, 'thus .handleconnectords also apparent.

forming a union stronger than either pair of wires forming it. Thisforms the wire vcore as before mentioned in a continuous loop.

The clamp which receives the handle -is disclosed at 6 and kthe same isprovided with a tubular portion 7 at its end through which the cross bar3 of the wire passes.. The cross bar serves as a bearing for a clamp tobe described.' The clamp is pro- .65. vided with two jaws'8 and 9 whichproject from Athe tubular portion 7 and which are connected by aclamping screw 10 and the linger operated nut 10 to enable them to bedrawn together to clamp any ordinary wooden handle 11 between them. v

The shape or design of the twisted wire core holding the bristles orother material is so formed or constructed that the handle connector orclamp 6 is placed in such a 75 position on the brush, that it may turnover or oscillate to the opposite sideof the brush. This permits thebrush to be utilized on either side without removing the handle from theclamp or handle connector.

This connector in which the handle is attached, by being able tooscillate on the axle vof the wire core, allows the brush to lie flatagainst any surface, regardless of the angle the handle is held, andwithout allowing any part or end of the wire core ofthe brush or anymetal part to come in contact with the surface being cleaned orpolished.

'F rom the foregoing it will be apparent 90 that the simple constructionof the brush makes it a' strong and sturdy article capable of hardusage. The welded joint at 5 for the ends of the wire core work l formssaid core into a continuous unbreak- '95 able loop.

The convenience of being able to `useboth top and bottom sides of thebrush to advantage without removing handle from the The lower cost ofmanufacture is also obvious, since the component parts -of wire andbristles are twisted together in one operation, thereby forming thebody, core and frame work of the brush, without the need of any binding,adhesive or otherv material, or any other operation to secure or applthe bristles to the frame ory core on whic the handle connector 6 isattached.

From the foregoing it is obvious that our 11e `invention is not to berestricted to the exact twisted together, with bristles held between vthe twisted wires, the end portions of the twisted wires both being bentinwardly to-v ward thecenter of the brush, one end portion being furtherbent to form a bearing,

the fourends of the two wire portions being overlapped'and lwelded toform a union immediately adjacent the said be'aring, the union being atthe bend connecting the bearingwith the other wire portion, a clampingelement rotatably mounted on the bearing,

and a handle carried by said clamping ele-- ment. j t

2. A brush formed of wires twisted together with bristles ,permanentlyheld between the twisted wires, the end portions of the twisted wiresbeing bent inwardly toward the center of the brush, one of the endportions being further bent to l'orm a bearing, the four ends of the twowire portions being overlapped and welded together so that the weld isimmediately adjacent the n bearing, a tubular sleeve surrounding thebearing and rotatable thereon, provided with a. pair of semi-cylindricalgripping jaws, a threaded element extending directly throughlsaid jawsabout midway of their length, and` a finger operated nut cooperatingwith thevthreaded element for drawing the jaws together for detachablygripping a handle therebetween. i
